It's happened to me a couple of times when reviewing too (and, as most of you guys know, I tend to waffle on some

), and it's really disheartening to see several hundred words disappear into cyberspace, never to be seen again
These days, I ALWAYS highlight and copy any entry,
before clicking on the submit button, just to be on the safe-side.
That said, for reviews etc. that I
know are going to be quite long-winded, I'll use Word - primarily to ensure spelling's kept as tight as possible
